I SHUTTLE-BOX."

Specification of Letters Patent. Patented Feb. 8, 1916.

Application filed March 8, 1915-. Serial No. 12,746.

the shuttle into the box is gradually but effectually slowed down and the shuttle held securely against either rebounding or working back more or less outtof the box,.which latter undesired action is a common fault with shuttle-boxes heretofore known, especially in the case of box looms, on account of the jars and vibration incident to the vertical shifting of the boxes.

According to this invention, the so-called swell forming one wall of the shuttle-box has associated with it a resilient lever fulcrumed at a fixed point in the box and having one arm adapted to bear yieldingly against the shuttle and the other arm adapted to bear yieldingly against the swell. In the preferred construction, the aforesaidlever is pivoted near the entrance end of the box and when the shuttle is fully home the lever bears against the inner end of the shuttle, that is, the end adjacent to the cloth.

In the accompanying drawing, Figure 1 is a front elevation of a set of shuttle-boxes provided with my improvement; Fig. 2 is a plan view of one of the boxes, the shuttle being shown in full lines partly entered into the box; and, Fig. 3 is a view similar to Fig.-

2 showing the shuttle fully home in the box.

In the drawing, a designates the fixed structure of one of a set of shuttle boxes of usual form, and b is the swell constituting the front wall of the box and pivoted at c to the structure a; the inner end of the swell 7) plays between the two forwardly projecting lugs cl connected by the pin 6 which is disposed outwardly of the swell.

f is the shuttle. v

On the pin e is freely fulcrumed the resilient lever designated as a whole by the reference character 9 and described in detail as follows: Said lever consists of a suitable length of spring wire formed into a helical coil h adapted to form the bearing or fulcrum portion of the lever and having one end extending first tangentially from the coil, as at i, and. then bent off in one direc- RIEDEL, a citi-,

tion andthen back upon itself in parallelism with the axis of thecoil to form the-rebend y, and having its other end bent off tangentially of the coil, as at k, and then bent back and forth several times in parallel relation to the axis of the coil to form the Wiping portion Z including the U s'haped portion m. The arm i j of the lever g is a short arm and the arm 16 Z m is a relativelylong arm. This lever is fulcrumed on the pin e,which is passed through its coil it.

The'short arm adjoins-theinner end of the box and its rebend j is adapted tobe impinged by the end ofthe swell: 6; its long arm projects in the opposite direction and is adapted to be impinged by the shuttle.

Presence of the shuttle'infthe box involves the resilient lever 9 being put under tension, the swell I) (forced outwardly by the shuttle) bearing against the arm 71 j of the lever and the shuttle against the arm 70 Z m of the lever.

When the shuttle enters the box, it encounters the wiping portion Z m of the arm 10 Z m of the lever and presses it outwardly; next it wipes against the swell and 1 presses it outwardly until the swell impinges against the arm i j of the lever. The shuttle is now subjected to a double frictional resistance, to wit, that imposed by the swell,

which is backed by the resilient lever, in and that imposed 7 turn backed by the shuttle, by the long arm of the lever on the shuttle. The result is the gradual but effectual stopping of the shuttle. Further, when the shuttle has been thus brought to a standstill it is held securely against either rebounding or working back out of the box, as an incident to the vertical shifting thereof or similar influences, by the long arm ofthe lever g, which it will be'noted bears against the shuttle at its relatively inner end and in the preferred adaptation more or less forward of the point (as n, Fig. 3) where the straight side of the shuttle merges into the bevel of its nose. When the shuttle is driven from the box the opposing resistance dimin of the U-shaped portion of the lever g is adapted to impinge against the swell b and prevent the pivotal movement of the arm is Z we of lever 9 toward the back of the box farther than the dotted position shown in Fig. 2 (even though the swell has reached its backward limit, by contact with the box at 0), thus to insure against any possibility of the nose of the shuttle bearing against 1L the portion Z m. ofthe lever relatively forward thereof instead of rearward.

Having thus fully described my invention, what I clann as new and desire to secure'by Letters Patent is:

and the other simultaneously engaged by the bevel of the shuttle adjoining the inner end of the box.

2. In combination, with the fixed structure and the movable swell of a shuttle-box and a shuttle in the box having beveled ends, a resilient lever fulcrumed in said structure and having one arm engaged by the swell and the other simultaneously engaged by the bevel of the shuttle adjoining the inner end of the box, said lever consisting of a wire spring having a coil forming its bearing portion and its ends forming the arms of the lever.

3. In combination, with the fixed structure and the movable swell of a shuttle-box, a resilient lever fulcrumed in said structure and having one arm adapted to be engaged by and including a yoke receiving the swell and the other arm simultaneously engaged by the shuttle on the latter entering the box, said yoke afiording limited movement of the lever relatively to the swell.

In testimony whereof I afiix my signature in presence of two witnesses.
